Headlight unit for motor vehicle - has front lens of light conducting elements packed into grid to produce narrow angle of emergence

摘要

The headlight unit for a motor vehicle has a lamp within a reflector. The light beam has a narrow angle of emergence and high light output is ensured. The grid (8) is made of light conducting elements packed closely and with parallel axes. The thick ness of the grid is at least eigt dias. of the separate light conducting elements. The thickness of the grid s basically determined by the relationship between a light conducting element dia. and the angle of total reflection of the conducting element material.
